Painting mixing cup with guide function

The present disclosure relates to the technical field of vehicle paint spraying, in particular to a painting mixing cup with guide function.

When painters paint, they need to pour paint, thinners, etc. into a hard container in proportion to mix paint. In the prior art, the paint mixing cup is arranged with a cover, which only has the function of sealing, and its structure and function are relatively simple. When mixing paint, the cover of the cup is opened, paint and thinner are introduced into the paint mixing cup in proportion, and then the mixed paint is directly poured into a fluid supply device such as a gravity cup. In the process of pouring the paint into the fluid supply device, because the opening of the paint mixing cup is large, the cup wall and opening of the paint mixing cup are polluted in a large area, and even the outer surface of the paint mixing cup wall is stained with paint. After the paint mixing cup is used, the cover and the upper edge of the cup are stick together because the opening is polluted by paint, which increases the difficulty of opening the cover next time. The opening of paint mixing cup is generally large, so it is difficult to control the flow of paint mixing cup, especially when the cup is full of paint, which leads to a large error in the amount of paint poured into fluid supply devices such as gravity cup. For another example, the volume of the paint mixing cup is larger than that of the gravity cup and other fluid supply devices, and it needs to pour the paint into the fluid supply device for many times, so when there is still some paint in the paint mixing cup and erroneous operation occurs, the paint flows out instantly in a large area after the paint mixing cup is dumped, causing pollution and waste. In particular, the caliber of large-volume paint mixing cups is relatively large, while the caliber of fluid supply devices such as gravity cups is generally small, so when the operator directly pours paint, the flow rate is too large, and the gravity cups are often washed down, resulting in paint waste.

A multifunctional paint mixing cup for vehicle paint spraying has appeared in the market. A paint leakage port is directly arranged on the opening of the paint mixing cup, as shown in. However, it cannot be equipped with a corresponding cup cover, and even if the cup cover is equipped, it cannot be sealed. At the same time, the paint in the paint mixing cup cannot be poured out, and it is necessary to repeatedly open and close the cup cover to pour the paint. That is, in the prior art, during the specific operation, the paint mixing cup is in a long-term open state, which leads to the continuous volatilization of toxic substances (such as formaldehyde) in the paint and pollutes the environment in the workplace.

Therefore, the prior art still needs to be improved and developed.

In view of the above shortcomings of the prior art, the purpose of the present disclosure aims to provide a painting mixing cup with guide function, which can cover the paint mixing cup and allow users to control the flow of poured paint more accurately.

To solve the above technical matters, the disclosed technical scheme of the present disclosure is as follows:

A painting mixing cup with guide function including a cup body, wherein a ring-shaped sealing surface is arranged on an inner surface of an upper edge of the cup body, and a clip angle between the ring-shaped sealing surface and a vertical plane is 2°˜6°; the cup body is arranged with a guide cover, and the guide cover includes a clamping sealing structure, and an inner surface of a first ring-shaped plate of the clamping sealing structure cooperates with the ring-shaped sealing surface to form a sealing structure.

According to the painting mixing cup, a fourth ring-shaped plate is horizontally arranged on the upper edge of the cup body and a fifth ring-shaped plate is vertically arranged on an outer edge of the fourth ring-shaped plate; a flanging is formed by the fourth ring-shaped plate and the fifth ring-shaped plate, and the flanging is adapted to the clamping sealing structure.

According to the painting mixing cup, the guide cover includes a cover body, and the clamping sealing structure is arranged at an outer edge of the cover body; the clamping sealing structure includes the first ring-shaped plate vertically arranged along the outer edge of the cover body, a second ring-shaped plate is horizontally arranged at an upper edge of the first ring-shaped plate, a third ring-shaped plate is vertically arranged at an outer edge of the second ring-shaped plate; a length of the third ring-shaped plate is greater than a length of the first ring-shaped plate; an accommodation space matched with the upper edge of the cover body is formed between the first ring-shaped plate and the third ring-shaped plate, and the accommodation space is used for accommodating the flanging; a ring-shaped ridge, matched with a lower edge of the fifth ring-shaped plate, is arranged on the third ring-shaped plate.

According to the painting mixing cup, a reinforcing portion and a guide channel are arranged on the cover body; a portion of the guide channel is arranged on the reinforcing portion and a remaining portion of the guide channel is arranged on the cover body; a balanced air hole is arranged on a corresponding position of the cover body.

According to the painting mixing cup, a ring-shaped hole with a notch is arranged at middle part of the cover body, and a vertical wall is arranged on an edge of the ring-shaped hole skipping the notch; a first cover is arranged on the vertical wall; an opening corresponding to the notch is arranged on the first cover; and a hole corresponding to the notch is arranged on the cover body; the notch, the opening and the hole form a guide hole, and the guide channel is arranged on the guide hole.

According to the painting mixing cup, the vertical wall and the first cover are higher than the cover body to form a convex platform reinforcing portion; and the opening is located above the notch.

According to the painting mixing cup, the vertical wall and the first cover are lower than the cover body to form a concave platform reinforcing portion, and the opening is located below the notch.

According to the painting mixing cup, an outer contour of the guide channel is a part of a cylindrical shape or a conical shape; an outlet of the guide channel is obliquely arranged in a direction from the outer edge of the cover body to the reinforcing portion, and the outlet is ellipse-shaped; and an end of the outlet near the outer edge of the cover body is higher than another end of the outlet near the reinforcing portion.

According to the painting mixing cup, a gap is formed between the clamping sealing structure and the guide channel.

According to the painting mixing cup, both the guide cover and the cup body are formed by injection molding at one time; both the guide channel and the balanced air hole are arranged with sealing plugs; both the cover body and the first cover are set as circular-shaped; and the guide channel and the balanced air hole are located at a same diameter of the cover body.

The painting mixing cup with guide function of the present disclosure realizes sealing by the cooperation between the inner surface of the first ring-shaped plate and the ring-shaped sealing surface, realizes a second sealing by the cooperation between the accommodation space and the flanging, and also realizes the locking function by the clamping cooperation between the ring-shaped ridge and the fifth ring-shaped plate, to complete the cover of the painting mixing cup. In addition, the guide channel of the guide cover and the balanced air hole ensure the smoothness of the paint flowing. Due to the twice sealing, the paint does not pollute the upper edge of the painting mixing cup, which avoids the adhesion between the cup cover and the upper edge of the cup body. Therefore, the guide cover can be used repeatedly.

Further, the reinforcing portion is arranged at the middle part of the guide cover to ensure the cover body does not deform during injection molding and ensure the strength of the guide cover. In addition, a small part of the guide channel is arranged on the edge of the reinforcing portion, so that the guide channel can obtain the support of the reinforcing portion, and most of the rest of the guide channel is arranged on the cover body, thus ensuring that when the paint mixing cup pours paint outward, the guide channel takes the connection part with the cover body as a fulcrum and the connection part with the reinforcing portion as a pull-back point, thus improving the strength and stability of the guide channel when pouring paint. Meanwhile, the balanced air hole is opened when pouring paint to ensure the fluency of pouring paint, and the diameter of the guide channel is much smaller than that of the paint mixing cup, so that the user can accurately control the pouring speed of the paint. Moreover, the guide channel arranged on the cover body has a positioning function, and in the transportation process of the guide covers, the guide covers can be overlapped with each other through the guide channel to save transportation space.

The present disclosure provides a painting mixing cup with guide function. To make the purpose, technical scheme and effect of the present disclosure clearer and more definite, the present disclosure is further explained in detail below. It should be understood that the specific embodiments described here are only used to explain the present disclosure, and are not used to limit the present disclosure.

The present disclosure provides a painting mixing cup with guide function, as shown in, including a cup body, wherein a ring-shaped sealing surfaceis arranged on an inner surface of an upper edge of the cup body. A clip anglebetween the ring-shaped sealing surfaceand a vertical plane is 2°˜6°; the cup bodyis arranged with a guide cover, and the guide coverincludes a clamping sealing structure. An inner surface of a first ring-shaped plateof the clamping sealing structurecooperates with the ring-shaped sealing surfaceto form a sealing structure. More specifically, the clip angleis 4°, and an inclination of the first ring-shaped plateis also 4°, which matches each other. It is more convenient to demould and does not affect the visual sense of the product.

Furthermore, as shown in, a fourth ring-shaped plateis horizontally arranged on an upper edge of the cup body; and a fifth ring-shaped plateis vertically arranged on an outer edge of the fourth ring-shaped plate. A flanging is formed between the fourth ring-shaped plateand the fifth ring-shaped plate, and the flanging is adapted to the clamping sealing structure.

The clamping sealing structurecan adopt a technical way known in the prior art, needs to match the upper edge of the paint mixing cup, and can be adjusted accordingly according to the structure of the paint mixing cup. Here is only one embodiment to illustrate, but it should not be limited to the embodiments cited in the present disclosure. The guide coverincludes a cover body, and the clamping sealing structureis arranged at the outer edge of the cover body. The clamping sealing structureincludes the first ring-shaped platevertically arranged along the outer edge of the cover body, a second ring-shaped plateis horizontally arranged at an upper edge of the first ring-shaped plate, a third ring-shaped plateis vertically arranged at an outer edge of the second ring-shaped plate; a length of the third ring-shaped plateis greater than a length of the first ring-shaped plate; an accommodation spacematched with the upper edge of the cover bodyis formed between the first ring-shaped plateand the third ring-shaped plate, and the accommodation spaceis used for accommodating the flanging. A ring-shaped ridge, matched with a lower edge of the fifth ring-shaped plate, is arranged on the third ring-shaped plate, so that the guide coveris locked with the cup bodyby the fifth ring-shaped plate, the accommodation spaceand the ring-shaped ridge; and a surface seal is formed by an inner surface of the first ring-shaped plateand the ring-shaped sealing surface, a second seal is formed by the accommodation spaceand the flanging, and the locking function is realized by the ring-shaped ridgeand the fifth ring-shaped plate.

As shown in, the guide coverincludes a cover bodyfor sealing the paint mixing cup, and the cover bodyis arranged with a reinforcing portionand a guide channel; a portion of the guide channelis arranged on the reinforcing portionand a remaining portion of the guide channelis arranged on the cover body. A balanced air holeis arranged on a corresponding position of the cover body. The guide channeland the balanced air holeare arranged with sealing plugs, respectively. When in use, the sealing plugsare taken off, and both the guide channeland the balanced air holeare in an open state. When a user tilts the paint mixing cup, paint material flows out of the guide channel, and the user can adjust the flow rate of the guide channelby adjusting the tilting angle of the paint mixing cup, and the guide channelonly pollute the environment around the outlet, thus greatly avoiding the situation of large-area pollution of the cup mouth of the paint mixing cup in the prior art. When not in use, the sealing plugsblock the guide channeland the balanced air hole, so that even if the paint mixing cup is knocked down or in a misoperation state, the paint material is not wasted in a large area.

To further describe the present disclosure, the reinforcing portion can be realized in various ways, such as a convex platform reinforcing portion(as shown in), a concave platform reinforcing portion(as shown in), or reinforcing ribs(as shown in). Of course, it is not limited to the ways listed in the present disclosure, and other ways can be adopted to realize the reinforcing portion.

As shown in, a ring-shaped holewith a notchis arranged at the middle part of the cover body, and a vertical wallis arranged on the edge of the ring-shaped holeskipping the notch. A first coveris arranged on the vertical wall; an openingcorresponding to the notchis arranged on the first cover; a holecorresponding to the notchis arranged on the cover body, that is, the holeis connected to the notch, and the notch, the openingand the holeform a guide hole. Specifically, the notch, the opening, the holeand the lacking part of the vertical wall form the guide hole, and the guide channelis arranged on the guide hole. In addition, the vertical walland the first coverare higher than the cover bodyto form the convex platform reinforcing portion, on which the openingis located above the notch. That is, the part (also called the lower edge) of the guide channelon the cover bodyis lower than the part (also called the upper edge) of the reinforcing portion. On the premise of the above advantages, when the paint mixing cup is poured, the paint first contacts the lower edge of the guide channel, while the upper edge of the guide channelexhausts a small amount of air during dumping, forming a buffer, which further improves the smoothness of the paint flowing. In addition, the paint contaminated on the inner surface of the first coverflows into the guide channelalong the opening, thus avoiding the paint residue contaminated on the inner surface of the first coverafter pouring paint.

Furthermore, an outer contour of the guide channelis a part of a cylindrical or a conical, most preferably a conical part. As shown in, an outletof the guide channelis obliquely arranged from the outer edge of the cover bodyto the reinforcing portion, and an endof the outletnear the outer edge of the cover bodyis higher than another endof the outletnear the reinforcing portion, and the outletis ellipse-shaped. When the paint mixing cup returns to the vertical state after the paint is poured, because the openingis located above and behind the hole, at this time, part of the air enters the openingfirst, and the higher endblocks the paint outflow, and the lower endblocks the paint outflow more smoothly under the paint's gravity and in cooperation with the opening, and ensures that the paint does not overflow when the flow is stopped, so that the flow is stopped more stable.

To further ensure that the guide coverdoes not deform during demoulding and maintains its strength, the cover bodyis set as circular-shaped, and the reinforcing part also is set as circular-shaped, that is, a center of the cover bodyand a center of the first coverare located on the same straight line, and a diameter of the first coveris one third to two thirds of the diameter of the cover body, which not only ensures that the guide coverdoes not deform during demoulding, but also ensures the use strength of the guide cover.

In addition, a gap is formed between the clamping sealing structureand the guide channel, which ensures the strength of the guide channel, and ensures that the clamping sealing structureand the guide channeldo not shrink during molding and demoulding.

In addition, the convex platform reinforcing portionis higher than the cover body, and the outletis inclined to the direction of the convex platform reinforcing portion, so when the sealing plugis inserted into the guide channel, If the force is too large, the guide channelbends to the direction of the convex platform reinforcing portionto release the force, thus avoiding the overturning of the paint mixing cup caused by the excessive force. Furthermore, the higher endis higher than the height of the clamping sealing structureto ensure that the paint is smoothly led out and does not remain on the outer surface of the cover body, thereby reducing the pollution surface of the paint mixing cup during the paint pouring process. In addition, both the guide channeland the convex platform reinforcing portionprotrude upward in the same direction, so that positioning is carried out by the guide channel, and the upper and lower adjacent convex platform reinforcing portionsare exactly buckled together, so that positioning can be realized by the guide channelin the transportation process of the guide covers, so that a plurality of guide covers are overlapped together to save transportation space.

In another embodiment, as shown in, the vertical walland the first coverare lower than the cover bodyto form the concave platform reinforcing portion, and the openingis located below the notch. The general situation is basically the same as the above-mentioned embodiment, so it is not detailed here. The difference is that the concave platform reinforcing portionis concave to invade the volume of the paint mixing cup when the guide cover is buckled on the paint mixing cup, so the height of the concave platform reinforcing portionneeds to be controlled more accurately.

In another embodiment, the reinforcing portion includes at least one ring-shaped reinforcing rib. As shown in, the reinforcing portion includes two ring-shaped reinforcing ribs; part of the guide channelis arranged on the outer ring-shaped reinforcing rib. The ring-shaped reinforcing ribis located in the middle of the cover body. The difference is that, when using ring-shaped reinforcing ribs, due to the different wall thicknesses, the ring-shaped reinforcing ribsand the cover bodymay shrink, which may lead to the deformation of the guide cover.

In another embodiment, the guide cover is formed by injection molding at one time, which reduces the cost and improves the machining accuracy. Of course, other technology can also be used. Both the cover bodyand the first coverare circular-shaped. Moreover, the balanced air holeis generally arranged on the cover body, and the closer it is to the first ring-shaped plate, the better. However, a gap is arranged between the side wall of the balanced air holeand the outer surface of the first ring-shaped plate, which avoids shrinkage during injection molding. Moreover, the guide channeland the balanced air holeare located at the same diameter of the cover body, which is the best embodiment. No matter how the cover bodyrotates, the distance between the guide channeland the balanced air holeis always in the farthest state, especially when the convex platform reinforcement is used, even if the paint in the paint mixing cup is full, the paint does not pour out from the balanced air holewhen pouring the paint, thus improving the stability of use.

Of course, the above-mentioned description is just preferred embodiments of the present disclosure and the present disclosure is not limited to enumerating the above embodiments. It should be noted that all equivalent substitutions and obvious variants made by anyone skilled in the field under the teaching of this description fall within the essential scope of the present disclosure and should be protected by the present disclosure.
